Antero Resources — Jul 29, 2026 release

The Martica transaction was entered into in 2020 and included overriding royalty interests in Antero’s development program. Following return thresholds being achieved in the second quarter of 2026, these overriding royalty interests reverted to Antero. This is expected to result in a $60 million increase in annualized cash flow to Antero, or a $0.04 per Mcfe margin uplift, commencing in the third quarter of 2026.   Cash Cost Reduction Initiative   In June 2026, Antero announced a cash cost reduction initiative. Through this plan, the Company expects to reduce cash costs by $0.70 per Mcfe from full year 2025 to year end 2028. As a result of the lower cost structure, Antero expects to improve EBITDAX margins by $0.35 per Mcfe. These cost reductions and margin enhancements are expected to be driven primarily by the integration of HG Energy, natural gas and liquids firm transportation commitment optimization and increased dry gas development.   Share Repurchase Program   During the quarter, Antero purchased 1.1 million shares for approximately $38 million, for an average weighted price of $34.25 per share. Antero has approximately $880 million of capacity remaining under its share repurchase program.   Natural Gas Hedge Program   The following tables detail Antero’s natural gas swap and collar hedge position as of the publication of July 29, 2026.
